Regulates Tat transactivation activity through direct interaction. May be a cellular factor for HIV-1 gene expression and viral replication.
Involvement in disease
Defects in SART3 are the cause of disseminated superficial actinic porokeratosis type 1 (DSAP1) [MIM:175900]. DSAP1 is an autosomal dominant disorder, characterized by multiple superficial keratotic lesions surrounded by a slightly raised keratotic border, developing during the third or fourth decade of life on sun-exposed areas of skin.
Phosphorylated upon DNA damage, probably by ATM or ATR.
Cytoplasm. Nucleus speckle. Localized in speckles. Expressed in the nucleus of all of the malignant tumor cell lines tested and the majority of cancer tissues with various histologies, including squamous cell carcinomas (SCC), adenocarcinomas, melanomas and leukemias cells. However, this protein is undetectable in the nucleus of any cell lines of nonmalignant cells or normal tissues, except for the testis. Expressed in the cytoplasm of all the proliferating cells, including normal and malignant cells, but not in normal tissues, except for the testis and the fetal liver.
